How to play Tekken 8 in full screen mode

I’ve just installed Tekken 8 on Lutris and it’s playing in window mode - how can I get it to play in full screen mode? Thanks in advance

I’m using wine version wine-ge-8-25-x86_64

Have you tried to adjust it in-game with graphics options set to Borderless or Full Screen?
Is selected resolution for Tekken smaller than native monitor resolution?
